During the French and
Indian War, the British had all the advantages, and launched their final
campaign against the French, who were refugees in Montreal; all
their supplies were cut off, the British dominated by all directions
access to the city, and the Iroquois Indians gave them their military
support. In the summer of 1760, the British attacked by
three fronts of war, an army of 3,000 soldiers left from Quebec to the
West, by the Saint Lawrence. A larger army (3,500 soldiers)
advanced north from Lake Champlain, and a third army, the largest of
them, with 11,000 soldiers, used Lake Ontario to sail to Montreal. The governor of Montreal surrendered, and the city was won without battle, 8 of September of 1760.
